Immersing the crystals of 1 in THF solution led to the dynamic framework of 1 undergoing a crystal-to-crystal guest-exchange process to afford the helical metallacyclic polymer [Co(SCN)2(EDPC)2(THF)]n [1THF]. The guest THF molecules were accommodated in the cavities of the metallacyclic chains and showed the handness of the helical chains by their oxygen atoms as probes. %I ACS Publications
